do pest-deterrent plants affect "good" insects

Planning on adding oregano, basil, marigolds, citronella geranium, etc. throughout my planting beds. But I got to thinking that their "stinkiness" might hinder pollinators and beneficial predators.
All help/suggestions are appreciated - ESPECIALLY as related to Zone 4. Wishing ALL abundant harvest in 2019!

A lot of these plants actually attract pollinators because of their composite flowers, so, don't be afraid to plant them!

Just adding to this thread as their seems to be a fair amount of past testing that may aid the gardener in pest control.  The study below alludes to the possibility of making water extracts of weed and other plants that, in crude form and sprayed on to plants needing protection, can reduce predation by the pests often without harming beneficial insects.  It seems a low-tech and more Permie compatible pest control measure than the battery of chemicals often recommended.  Have others tried this?

Yes, I forgot to mention tansy - I've got many year-old plants I was going to spread around! Most of the others are seedlings.
But I still don't know how these deterrents might negatively affect parasitic wasps and other beneficial insects.
Thanks for help - please keep it coming! ;-)

Here is at least one other link that directly addresses the effects on non-target insects.  I have not read the paper thoroughly enough to see if they provide additional references to that concern, but perhaps there are some among some of the citations at the end of the paper.  I think it may be an important untapped resource for many home gardeners.  As many Permie 'growie' issues focus locally, it could easily be a case where tansy in one sub-region is more potent than tansy in another for antifeeding qualities.....and the same could be true for the myriad other plants in the vicinity of one's garden.  The combinations of plant extracts and pests to control might seem of daunting number, but the low-tech and environmentally-friendly nature of the idea is quite compelling.
